Diane, Juan met in RT Lab

To Dos ( 2/20/2019):

• Research interference between sensors (look at noise, accuracy), vibrations (including strength of FG) for first look at distancing
• Map sensor locations
• Look into mapping during nose cone layup (easier with two separate halves)
• Look into location of payload stack in CAD to find where the DAQ interfaces with the thermocouples relative to the base of the nose cone
• Determine wire length for thermocouples to cut, the shorter the wire the more accurate reading (less resistance), reduce mass, reduce load
  • Consider cable management system (looping wire near the DAQ, calibrate for extra resistance)
• Vibe Test
  • Test different locations 
  • Criteria: noise, accuracy
• Consider internal camera for performance for future scientific payloads

2/23/2019:

• First experiment will test 0 degree angle shift between two layers of 3 TC's, X inches apart (to be determined)
• Potential Wiring Strategies:
  • Single continuous loop, across different contours (see diagram A below):
  • 3 lines of TC pairs according to blackboard diagram (see diagram B below):
    
• For first experiment, use the following jig (lasercut) for each layer (apply epoxy first, then use jig)
  • Need diameters for contours on which to apply  TCs
    
• Consider using 3D printed support structures (see below) 
  
  • Concern for strength/adhesion on launch
  • Ideally thin, and epoxied along inner surface of NC
  • Combine jig and ring for mounting (void) and support 
  •

Determined first method of thermocouple attachment: steel rod jig w/ aluminum tape or string quick-release knots

Determined distance from base of NC to DAQ-TC interface: height = 3.08", ID =
